The private server City of Heroes Homecoming has started a witch hunt to locate the characters that infringe copyright from other brands.
Basically no more making a copy of Superman, Spiderman, Batman or any famous superhero.
“Today we have published an update of our Code of conduct. The main change is that we no longer allow characters to use copyrighted material owned by other companies. We don’t want to draw the ire of Marvel, DC, or other giant entities and unnecessarily put Homecoming at risk.
Characters using copyrighted materials will have their name and/or costume reset. Then you can select a new name and create a new costume the next time you go in.”
